If I had won the big lottery a few weeks ago, my personal
flight department would be these airplanes...
A Beechjet 400A (now called a Hawker 400) since I am already
typed in it.
A Beech 1900 to carry my Harleys around to Sturgis(typed in
that too.)
A Helio Courier on floats
A Legacy Cub
A G36 Bonanza
A Pitts S2
A Skipper with a big engine
A Duchess with two bigger engines and floats

Aha. No round engines in the list, I see...
